Hi, Bjoern,

 

Thanks for your reply! What shuld I do if I want to limit the exact accurrance for each sub-element in the element Gragh? I mean I want to have:

0 or more "PCDATA" and "n" but 1 or more "img" in it.

 

Cheers,

syt
<!ELEMENT Graph (#PCDATA|n|img)*>

If you have mixed content you only constrain which child elements are
allowed, not the order in which they have to occur or their number:

<!ELEMENT Graph (#PCDATA|n|img)*>

See http://www.w3.org/TR/xml/#sec-mixed-content for more information.
